Question 1

AHRS 1 OVHT
AHRS 2 OVHT
AHRS 1-2 OVHT
(YELLOW)

Answer 1

AHRS 1, 2 or both overheated or shutdown

Failure of AHRS 1 will cause illumination of the weather radar STAB amber MFD indication and a FUEL QTY FAULT white CAS. Fuel quanitity will be correct at 0 degree pitch attitude.

Question 2

CNFG MISMATCH (YELLOW)

Answer 2

The configuration between the Integrated computer configuration Modules (IMs) does not agree.

Question 3

DUA 1A FAIL
DUA 1B FAIL
DUA 1A-1B FAIL
(YELLOW)

Answer 3

1A or 1B, or combination, DAU channel failed

Question 4

DUA 2A FAIL
DUA 2B FAIL
DUA 2A-2B FAIL
(YELLOW)

Answer 4

2A or 2B, or combination, DAU channel failed

DAU CHannel 1A and 2B are noramlly displayed. The loss of DAU 1B does not affect the displayed data unless reverted to DAU B.

Question 5

L DAU ENG MISCMP
R DAU ENG MISCMP
(YELLOW)

Answer 5

Respective IC-600 has detected miscompare between Channels A & B of DAU

During DAU reversion, the miscompare CAS will extinguish. The DAU A REV or DAU B REV white CAS will be illuminated.

Question 6

L DAU SYS MISCMP
R DAU SYS MISCMP
